PURPOSE: To determine if spermatozoa are present in the preejaculatory penile secretion, originating from Cowper’s gland. METHODS: DESIGN: Prospective clinical and laboratory study. SETTING: Andrology and Sex Counseling Unit, Department of Obstetrics and Gynecology, Academic Teaching Hospital. PATIENTS: Five patients referred for premature ejaculation, three for excessive fluid secreted during foreplay and four normal healthy volunteers. INTERVENTION: Glass slide smears of preejaculatory Cowper’s gland secretion obtained during foreplay from at least two different occasions, and semen samples after masturbation. MAIN OUTCOME MEASURES: Microscopic examination of air-dried smears, and routine semen analyses. RESULTS: None of the preejaculatory samples contained sperm. All the patients had sperm in routine sperm analyses. CONCLUSIONS: Preejaculatory fluid secreted at the tip of the urethra from Cowper’s gland during sexual stimulation did not contain sperm and therefore cannot be responsible for pregnancies during coitus interruptus.

I think many people are afraid of the 0.0001% chance that it will contain some viable sperm from a previous ejaculation, and get someone pregnant.

I tried taking pygeum but it does not seem to increase the volume of precum.

I never heard precum was the most potent, but I did hear that it could possibly cause pregnancy. I think the problem with coitus interuptus, even if precum is not fertile, is that there is not a clear line between what is precum, and what is a partial ejaculation. I know a lot of times you can try to dissipate your urge to cum and lose a little fluid, but this could be potent ejaculate, rather than the normal precum. That’s just my theory, anyway.

Five men is a very, very tiny study indeed. What happens in a clinical lab and what happens when you are in private, shaft against vagina, are very different events. Be cautious, is all I have to say about this one.

Any latest news about how to increase the volume of precum?

My Q is what does the absence of precum indicate? I use to know the answer to this but I forgot?

Interesting, but it has a very poor control …

So its not my baby!

"Well, people from Tennessee are generaly good at whatever it is they do even though they usually have no clue what they're doing."

Pregnancies in couples using the withdrawal method are probably due to mini-ejaculations occurring without the guy’s knowledge, as Mravg suggests. It appears that pre-cum doesn’t contain any viable sperm.

They may just have been taking a crude and practical approach to presenting the fact that guys who rely on trying to withdraw before they ejaculate as a method of contraception, have a fairly high chance of getting a gal pregnant. Or even using scare tactics.

It would certainly be logical to assume that pre-cum was potent, not knowing the exact mechanism for why the withdrawal method can still result in pregnancy.
